Application filed August 19,1925. Serial No. 51,185. I

Thisinvention:relates to aivending machine primarily adapted for use -1I1 connection with pencils although its principles may obviously be applied to vending machines or the equivalent generally. p

Itis aimed to provide anovel construction for operation through the turning of acrank' ortshaft upon deposit fa proper com in rdergto operate the parts; and release the Another object is to provide a construction employing relatively movable,'coacting elements in combinationwith a coin to deposit the latterwwithin the collecting box of themachine and to thereafter release the pencil. v y a a y i Another object is toprovide a novel means whereby the pencils may be agitated as each vending operation occurs, in order to insure straight feeding of the pencils or alinement while withinfthemachine. a a i Another object is to provideanovel construction wherein an endless advertisingclcment is employed in connection with a motor, the latter being adapted to operatea pencil sharpener, and controlled soas to operate only when a pencil is in engagement with the; sharpener. y I a advantages will become more apparent from a consideration of the description following taken inconnection with accompanying drawings illustrati of operation. 7 7

Figure 6 is a detail sectional View taken on line 6-6 of Figure 1 with an operating coin in initial position, and i Figures 7 and 8 are VIGWSSllTlllflI to Figure 6 showing the parts in different stages Referring s )ecifical1y to the drawings, a suitable type of casing is provided as generally design ated A, which for instance, may be rectangular I in cross section as shown employing a bottom ori basewall 10, a back or rear wall 1 1, sidewalls 12, a frontgwall 13 and a top Wall 14. In order that the casing may be opened, walls 13 and 14 are walls 12. Spanning the uprights 16;and 17 are side walls Bran d719, whichare fastened to the walls 16 and 17 in any suitable manner as by thepassage Of lugs v20 thereon through openings inthe walls 16 and 1-7 and subsequent clinchingithereofQ vWall 19 has anintegral downwardly and inwardly inclined bottom portion at 2.1,YAtdihe lower portion of the wall 18, a bottom wall 22 is provided, however being pivotally connected asat 23 on: a'suitable rod 23Fmonntedin the walls 1.6 and 17. The parts justdeany commodity but which obviously may be scribed constitute a hopper generally designated H which is usually of a size tohold a gross of pencils P or desired quantity of of anysize preferred; The pencils or commodity may be viewed threugh window 13? in Wall 13. Walls 21 and 22 have ano u tlet passage 24 between them whichuis idefined-by depending walls or flange/s25 and 26 respectively integral with them. The

jpencils P are adaptedto be vended or discharged one at a time through the deposit of a coin as suggested at 27 (Figs, 6-to 8) through a slot 28 in the front wall 13 and passage-way 28 within the machine the pencils traveling down a guide plate 29 prefer- V ably inclined as shown, throughian opening 7 30 in the wall 13 and ontoa supporting rack orrelemen t 31disposed exteriorly of the ma chine sothat the pencil may be manually removed. i

a contractile spring 35 secured thereto and The coin 27 upon reaching the interior of thei machine abuts the forwar'dend 32 Ottalever 33." Lever 33 is pivotediat 34 to wall 17 and isurged upwardly at the coin endby journaled for rocking to wall 17, the u ward movement of such lever being limite by a suitable stop 33" on wall 17.

A filler 27 if necessary may be fitted to the inner surface of wall 13 in passageway 28 so that the coin will be held by same and lever 33 untilthe machine is operated and to form an operating connector.

A rock shaft 36 is journaled in wall 17 and has a crank 37 thereon which has a pin and enlarged slot connection as at 38 with the lever 33 so that as the lever 33 is operated, ,the crank 37 will turn the shaft 36 one quarter of a revolution. Shaft 36 has spaced retainers 39 thereon between which a pencil P is adapted to be received for discharge to the end that through the one quarter revolution before referred to, the pencil will be discharged onto the guide 29.

Retainers 39 normall abut the lower edges of flanges 25 and 26 ig. 4). Each retainer 39 has a cam 40 of such shape that it is normall in direct supporting engagement with the ower end of wall 26 at cutaway ortions 26 and as the shaft 36 is rocke forwardly on its one quarter revolution heretofore referred to, said cams will tilt the wall 22 so as to insure alinernent of the remaining pencils with the passageway 24, and will also extend under the pencils next to be discharged so as to prevent discharge until the shaft 36 returns to normal position and likewise the retainers 39 return to normal position and engage the remaining encils.

The mac ine has an operating shaft 41 in the wall 17 and adjacent wall 12. aid shaft 41 has a manipulating crank 42 extending to the exterior of the machine and said crank has a guard and ejector element or plate 43 rigid therewith. Plate 43 has a projection 42" which normall is opposite a shoulder 34 on lever 33, being urged to that position by a contractile spring 44connected to the plate 17 and to the crank 42, so that the lever 33 cannot be accidentally actuated.

In operation, say a coin of predetermined size or value is deposited in the slot 28 by the purchaser, it will engage filler 27 a and the nose or shoulder 32 of lever 33 as in Figure 6. The coin thus forms an 0 rating connector and the purchaser then rit resses crank 42, rocking shaft 41. As a resu t, and as shown in Figure 7, projection 42 is moved away from shoulder 34 and the plate or ejector 43 engages the coin and depresses it past the lever 33, the lever 33 swinging on its pivot 34 to accommodate such movement, and the coin then falls into a removable collection box or tray 45. The movement of lever 33 is imparted to crank 37 which! rocks shaft 36 forwardly and causes the retainers 39 to discharge the engaged pencil P onto the guide 29 so that it may roll exteriorl of the machine and into engagement with the rack 31 for manual removal by the purchaser. As the shaft 36 rocks, the cams 40 tilt the wall 22 to agitate the pencils to maintain them in proper alinement and engage under the lowest pencil remaining in the machine or passageway 24 so as to re vent premature discharge thereof be ore deposit of the proper coin by the next purchaser. The s rings 35 and 44 return the parts to norma position after operation.

Plate 43 performs a further function in that in operation it guards passageway 28 against more than one coinbeing received at a time, since it will eject a second coin as suggested in Figure 8. I

It will be noted that considerablespace is provided within the casing not occupied by the mechanism referred to and therein supported on the base 10 is a suitable electric motor M, deriving its current from any suitable source.

thus establishing the electric circuit throughv the motor and maintainin such circuit established until the pencil is removed, whereupon the spring of contact 49 will move it out of engagement with contact 50.

Within the machine at one side thereof in a space S, a suitable flexible endless tape 51 is provided which has suitable advertising or ot er data delineated thereon adapted to be displayed through a window or opening 52 inthe wall 13 opposite the space S. This tape passes over suitably journalled 'uide rods or pins 53 and over two sprocket w eels 54 which are keyed to the shaft 36. The sprocket wheels 54have their teeth 54 in mesh with slots 55 provided adjacent the borders of the tape 51. By this sprocket connection with the shaft 36, the tapewill be driven a limited distance, each time the machine is operated and through such operation. The sprocket wheels 54 areloose on shaft 36 and have pawls 56 engaging ratchets 57 on shaft 36 so thatthe wheels 54 will properly coact with said shaft by turning in one direction only and slipping when the shaft is turned in the o poslte direction to avoid injury to the tape y retrograde movement of said shaft. 1

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

What is claimed is 1. A vending machine having a lever adapted to receive a coin thereagainst, ara rock shaft, means on said shaft engageable ticle-dischar ing means operable through with the article to be vended to discharge the 10 movement or the lever, an ejector engageable same, a crank on said shaft, a lever engaging with the coin to shift the lever and deposit said crank and arranged for deposit of a 5 the coin in the machine, said ejectorhaving coin against the same, and means operable a portion normally opposite the lever and to move the coin to operate the lever. preventing actuation thereof by a coin. 'In testimony whereof I affix my si ature.
